Sample questions

A few real prompts from the game to help you choose an activity for your class.

  1. Put the factors of 24 in order from smallest to largest.

    • 1
    • 2
    • 3
    • 4
    Read the explanation

    One, two, three and four are the first four factors of twenty-four.

  2. Put the decimals in order from smallest to largest.

    • 0.1
    • 0.4
    • 0.7
    • 0.9
    Read the explanation

    Compare the first decimal place.

  3. Put the steps of finding the highest common factor in order.

    • find the ones they share
    • list the factors of the first number
    • list the factors of the second number
    • take the largest
    Read the explanation

    You need the factors of both numbers before you can find the common ones.

Game teaching guide

What children will practise

Order one-place decimals (indicator ค 1.1 ป.4/6), order numbers with different numbers of digits, order factors, and put the steps for finding a highest common factor in order, groundwork for the HCF indicator ค 1.1 ป.6/4, which the curriculum places in P6.

What's in the worksheet

4 ordering questions - The given factors of 24 (1, 2, 3, 4) smallest to largest - 0.1, 0.4, 0.7, 0.9 smallest to largest - Steps for the HCF: factors of the first number, of the second, find the shared ones, take the largest - 8210, 4560, 2340, 980 largest to smallest

How to use it in class

Use as a short 4-5 minute game, solo mode; Q1 and Q2 are easy warm-ups. - 980 is the only three-digit number, so it must come last - If HCF has not been taught, demonstrate with 8 and 12 before playing - Extend Q1 by having pupils list every factor of 24 (1, 2, 3, 4, 6, 8, 12, 24) - Play it linked to the class to record results in the mark book

Common sticking points

- Placing 980 before 2340 because 9 looks big. Count the digits first - Swapping "factors of the first number" and "of the second", which really can be done in either order, but the game accepts only one; if a pupil swaps them and can explain, count the understanding as sound - Putting "take the largest" before "find the shared ones", not yet understanding "common"

Play together first, then build on it with a worksheet for the same level.
